close popup when parent window is closed

Hi everybody,

I have written a bsp application with one page.

If the user clicks on a submitt-button a new window is opened by calling the

javascript function window.open.

Now I am looking for a way to close the sub-window automatically when the parent window is closed.

I have found the attribute "dependent" in the window.close function, but this only

works for netscape and nor internet explorer.

Could you help me

Best regards & Thanks a lot

Alberto
